Residents have been asking why they are seeing trees being removed or prepped for removal throughout the City.
If you’ve noticed missing trees from public areas (parks, trails, medians), it is more than likely because they were Ash trees that were in fair or poor condition. This is being done in preparation for Emerald Ash Borer (EAB), an invasive species that targets ash trees.
The City of Plano is actively replacing Ash species with hardy, native and/or well adapted trees that grow in our area. Tree replacements occur during tree planting season (November to March) and where irrigation is available. This is an example of why diversifying our species within the City is so important!
EAB is an invasive species that has destroyed millions of Ash trees across the country. The beetle was discovered in the US in 2002 and in Texas in 2016. In 2018, EAB was found in Tarrant County. City staff has been watching the situation and working closely with the Texas A&M AgriLife Extension and Texas A&M Forest Service.
EAB has not been found in Plano or Collin County.
The beetle reproduces by laying its eggs in ash trees and is very aggressive, causing ash trees to die within two or three years after they become infested. Plano’s tree canopy consists of 6 percent ash, meaning Plano’s tree canopy will be impacted by this insect.
So, what is the City of Plano doing as preventative measures? Our goal is to continue to grow Plano’s tree canopy while reducing the negative impact of this insect. Throughout 2019, the Parks and Recreation Department inventoried the health of all ash trees on public property. EAB is only a threat to ash trees and will not affect people or other species of trees.
If you have an ash tree on your property that is in poor condition, please consider removing it. Citizens who wish to save their ash trees should consider the systemic insecticide TREE-äge, Emamectin Benzoate: 4.0%. This will not be necessary until EAB has been discovered within 15 miles of Plano’s border.
Texas A&M Forest Service is monitoring the situation and provides information about EAB on their website. To report EAB siting’s, contact the hotline 1-866-322-4512. For questions regarding Plano’s plan for EAB, contact Angela Kralik email@example.com or visit plano.gov/trees.
